' Be it known that WESLEY A. PAUL, late a citizenof the United States and a resident of Moline,.in the county of Rock Island and State of Illinois, did invent certain new and useful Improvements in Cultivators, ,of which the following is a specification, reference abeing had therein to the accompanying drawing. v p

The invention relates to cultivators par ticularly to that type in which the earth treating members are arranged .in gangs, and the object .of my invention is to provide means for adjusting the gangs to di'iierent positions that are necessary for proper cultivation.

Referring to the drawings, in which similar numerals-indicate identical parts, there is shown .one gang of disks only where two are normally employed to operate on opposite sides of ,a' row of plants. Both gangs however have a similarconstruction and are a d- :justed in a similar mannensothat a descriptionof one will suifice for both.

Figure 1 isla plan .view. of a gang of disks connected to alcultivator beam.

Fig. 2 is a rear elevation of Fig. 1. Fig.3 is a sideelevationof Fig. '1. Figs. 4; and 5 are enlarged detail sections. Fig. 6 is a modification of the device illustrating a gang ofcultivator shovels connected therew1th,.and

Fig. 7 is a plan view of Fig. 6.

As illustrated 1 is a cultivator beam adapted to be connected at its'forward end to the frame of a cultivator. Extendinglaterally from the rear end of the beam 1, and preferably :integral therewith, are arms 2 to which :is rigidly secured a bar 3 having a series of notches aiinthedower edge thereof. Mounted on the bar-:3 is a bracket 5lformed with projecting portions 6 which overlap the upper and lower edges ofthe bar 3 forming a guideway for "lateral adjustment of the :bracket 5. The .upperand lowerportions of the-bracket .5 project rearwardly and terminatein vertical'bearings Tin which is journaled the verticalportion of a spindleS having; its lower end 9.bent,at a right angle to the vertical portion and-extended .rearward. The upper end of the spindle ,8 is squared and l1as=.clamped ,-,thereon rr-igidly, byaJoolt lO,;a;member:.ll:.haVing a longitu- Specification of Letters Patent. Patented Dec. '25, 1917.

dinal slot 12in which is pivotally mounted a dog 13 adapted to be rocked by operation of an a y L. r .7

" The dog 13 operates a box 15 in the i I are bearings 19 andl20', of a well knownt'ype,

having .jo'urnaled' therein a shaft upon which are mounted Idisks 121 in a manner well known in the art, the disks heingfree lto revolve. i i I ,dleBIpTojects and held'thereinhy a cotter 22; at.thea1 pper end of the vertical arm' 17 .1s plvotallymounted a dog 23which .is rock} ln the top ofthe box is formed a bearing-through whiclithe portionfi of the spinb ,by means of an arm 24 preferably -tegral therewith; the dog 24: is adapted to engage with anyone of a seriesflof notches in a'segment '25 on a rearwardly extending portion of the .member 11, .the dog held in normal engagement with any one ofsaid notches in the segment 25 by a coil spring a which is secured between a reariward extension 6 of the arm 24;.and'aproection 0 on the vertical arm 17 Pivotally mounted 111 a recess .26 in.the

lower part of the 'bra ckete a dog 27 .adapte d to engage with the notches 4 inlthe bar ,3 and retained in such engagementhy acoiled spring 28 secured hetweenthe lower wall of the recess 26 and a projection 29 on the dog 27 ;-:by operating anarm 30, extendingrearwardly from thedog 27,;and preferably integral therewith; the "dog 27 is rocked .upon its pivot to disengage lit ,from.;the notchesfl in the bar 3. I i

the manner of at- Figs. 6 and 7 illustrate a .taching vagang of shovels removing the yoke from? the portion 9 ofthe spindle .8 and sulqstituting therfeifor a vertical member bolted beams 35 and 36 forming supports for 7 standards 37 carrying shovels or any; desired type.

The upper endof the member 31 is provided with means to engagewith the segment 25 similar to those employed with the yoke,and the same numerals are employed in each case.

The improvements shown constitute various adjustments by which the cultivating devices employed can be adapted to different conditions of cultivation; to move a gang toward or from the center of the cultivator for wide or narrow rows, operate the arm 30 to release the dog 27 from the notch in the bar 3, with which it maybe engaged, freeing the bracket 5 so that can be moved on the bar-3 in the direction desired, and secured-in its new'position by the dog 3 engaging with the adjacent notch. To angle the gangs horizontally the dog 13 is released from the notched segment 16 so as to allow the spindle 8 to be turned in its hearings on the bracket 5 until the cultivating gang has been adjusted as desired, when the dog 13 is again engaged with the notched segment 16 and the gang is held against further horizontal movement. In adjusting the gangs for operation with hilled or furrowed crops and it is desired to tilt the gangs at an angle to the horizontal, the dog 24 is disengaged from the segment 25 by pressure on the extension I) and the gang is free to be tilted, rocking on the portion 9 of the spindle 8, to the position desired where it can be held by the dog 23 engaging with the notched segment 25. The same adjustments are utilized for the shovel gang as will be readily understood.

Using any type of cultivating devices, they can be readily adjusted to varied positions as the work may require when mounted similar to the devices shown and desaid bearings and having its lower end extending rearwardl-y, a gang of cultivating devices pivotally supported on the lower end of the spindle, and means for swinging the gang horizontally and for tilting it on said I pivotal supports.

" 2. In a cultivator, the combinationof a rearwardly extending beam, a laterally adjustable bracket supported on the beam and having bearings at the top and bottom thereof, a vertical spindle pivotally supported in said bearings and having its lower end extending rearwardly,,a,gang or cultivating devices pivotally supported on the lower end of the spindle, means for'swinging the gang horizontally and for tilting'it'o'n said pivotal supports, and means for holding it in any adjusted position.

3.- In a cultivator, the combinationof a rearwardly extending beam, a bracket sup ported on the beam and laterally adjustable to varying positions thereon, a bearing on the bracket above the beam, a bearing on the bracket below the beam, a' vertical spindle pivotally supported in said bearings and having its lower end extending rearwardly,

gang of cultivating devices pivotallysupported on the lower end of the spindle, means for swinging the gang horizontally and for tilting it on said pivotal supports, and means for holding it many adjusted position. I

In a cultivator, the combination of a beam, a bracket slidably supported on the beam and having its upper and lower ends extended rearwardly, bearings in said ends, a vertical spindle journaled to oscillatein said bearings and having its lower end extending rearwardly, a gang of cultivating devices pivotally supported on the lower end of said spindle, meansfor swinging the gang horizontally and for tilting iton said pivotal supports, and means for holding it in any adjusted position. V

5. In a cultivator, the combinationof a beam, a bracket slidably-supported on the beam, a spindle vertically supported injbear ings on said bracket and having its lower end extending rearwardly, a, yoke having downwardly extending arms, one of said arms having a bearing in which the-lower end of the spindle is journaled, a gang of I:

6. In a cultivator, the combination of beam, a bracket slidably supported on the beam, a spindle vertically and rotatably supported in hearings on said bracket and having its lower end extending rearwardly, a notched segment horizontally disposed and mounted on the bracket, amember secured on the upper end of saidspindle and actuated to rotate the latter, a dog mounted on notches in said segment, a yoke having downwardly extending arms, one of said arms having a bearing in which the lower end of the spindle-is journaled, a gang of the arms of said y0ke,said yoke adapted to be rocked on the lower :end of the spindle to vary the position of the gang in a vertical said member and adapted to engage with the cultivating-devices supported in-bearings on direction, an upright segment on the member on the upper end of the spindle, and a dog on the apex of the yoke to engage with said segment to hold the gang in position.

7. In a cultivator, the combination of a rearwardly extending beam, a laterally extending bar secured to the rear end of the beam, a bracket slidably mounted in said bar for lateral adjustment, co-acting means on said bracket and bar to hold the latter in an adjusted position, bearings in the upper and lower ends of said bracket, a vertical spindle journaled in said bearings and having its lower end extending rearwardly, a gang of cultivating devices pivotally supported on 15 In testimony whereof I aifix my signature, 2o in presence of two witnesses.
